3 Claims. (Cl. 221-94) This invention relates to certain improvements ina portable liquid dispenser suitable for use in hospitals, nurseries,etc., for discharge in one operation of a considerable quantity ofliquid, such as soap, alcohol, lotion, and the like.

It is an object of the invention to provide a lower actuating meanswhich is in alignment with an upper discharge pipe whereby the liquidmay be dispensed and received with one hand; Another object is toprovide a dispenser with a pump unit which may be readily removed forinspection or repair. w

A suggestive embodiment of my invention is set forth in the accompanyingdrawing, in which- Figure 1 is a view in sectional elevation of thedispenser showing the piston in normal retracted position;

Fig. 2 is a fragmentary view in section of the upper end of thecontainer, the section being taken on the line 2 of Fig. 1; and

Fig. 3 is an enlarged fragmentary view in section of the lower end ofthe container showing the attachment of the tie rods to the base.

Referring to the drawing, the numeral 10 designates a base havingadjacent its outer edge an upstanding flange 11 and a depending skirt12. Seated on the base within the flan e and extending upwardlytherefrom is a cylindrical wall 13, the outer end of which is closed bya cover 14 having an annular flange 15 which may be extended over theedge of the wall. The cover is shown as provided centrally with a fillopening 16 and fill cap 17. The base, cylindrical wall and coverconstitute a container for the liquid to be dispensed. The container issecured together by tie bolts and base, each of the tie bolts beingprovided at one end with a head 21 for abutting the cover, the other endbeing provided with threads for receiving a screw 22. .A gasket 23, suchas rubber, or the like, covers the bottom side of the base, the screws22 extending therethrough to be secured to the tie bolts. To seal thecontainer the space between the wall and flanges 12 and 15 may be filledwith a suitable seal 24, such as litharge.

The liquid is dispensed from the container by a pump shown generally at25, which comprises a cylinder 26 secured as by threaded connection to ahead 27, having a flange 28 adapted to be secured to the base. The baseis provided with a large central opening 30 through which extends thepump cylinder and head, and is further provided with suitable bosses 31into which are 20 which extend through the cover the compression of thespring 65. As the piston threaded screws 32 for securing the head to thebase against the gasket 23.

Slidably fitted in the cylinder is apiston 35 secured to a piston rod 36by a cap 37. The piston rod extends through the head which is provided 0with a suitable packing gland 38'. The end of the piston rod, to whichis secured the piston, is provided with an axial bore 39 connecting witha transverse bore 40 below the piston. The piston rod end is beveled at41 to provide a seat 5 for a ball check valve 42, which is held againstdisplacement by the cap 37. The cap is perforated at 43 to permit theliquid to pass therethrough to the inside of the cylinder as the pistonmoves downwardly.

Radial openings 45 provide communication at all timesbetween thecontainer and the cylinder below the piston, and openings 46 providecommunication with the interior of the cylinder above the piston whenthe latter is in its normal position. An actuating lever 50 pivoted at51 extends through a slot 52 in the skirt, the outer end of the leversupporting a platform 53 upon a link 54. The purpose of the linkconnection on the platform is to provide a connection whereby theplatform may be held in an untilted position as the lever end movesthrough an arc. The lever extends at 55 beyond the pivot to contact withthe piston rod end.

A discharge pipe is secured to the end of the cylinder and connects witha suitable spout 61 which is secured to the cover and is locateddirectly above the platform. Preferably, the discharge pipe is removablyfitted to the spout so that the pump may be readily removed from thebase when necessary.

To operate the dispenser, the platform is depressed by the hand. inwhich may be held, a receptacle, to move the piston upwardly against ismoved upwardly the ball check valve is closed, also the openings 46 andthe liquid is forced out of the discharge pipe and spout, and into thereceptacle placed on the platform. When the pressure is released fromthe platform the spring forces the piston to normal position, thecylinder being partly filled with air through the discharge .pipe andpartly filled with liquid entering the cylinder through the check valve.When the piston is returned to its position, as shown in Fig. 1, theliquid in the container may flow through the openings 46 and 39displacing the air in the cylinder.

The device may be provided with a suitable 11o handle 66, such as a bentwire, having its ends pivotally connected to the tie bolt heads.

I claim:

1. A dispenser for liquids comprising a container having a top andbottom removably fitted thereto, a spout supported by the top, a pumpwithin the container supported upon the bottom and removable from thecontainer therewith, and a discharge pipe extending from the pump to thespout having a freely releasable connection with one whereby to rendereither the top or bottom free for removal from the container.

2. A liquid dispenser comprising a container having at its top a coverand at its bottom a base with an opening therein, a spout secured to thecover, tie rods for securing the cover and base together and to thecontainer, a pump cylinder having a peripheral flange at one endremovably secured to the base and closing the opening therein, therebeing an opening in the walls of the cylinder intermediate its ends, adischarge pipe connecting the cylinder with the spout, a piston in thecylinder adapted to be moved downwardly to a point below the openingtherein whereby liquid in the container may flow by gravity through thesaid opening to fill the cylinder and be forced out through thedischarge pipe when the piston is moved upwardly, and means exteriorlyof the base and in vertical alignment with the spout for operating thepiston;

3. A liquid dispenser comprising a container having at its top a coverand at its bottom a base with an opening therein, a spout secured to thecover, tie rods for securing the cover and base together and to thecontainer, a plate 'removably secured to the base to close the openingtherein, a pump cylinder secured to the plate and extendlng upwardlyinto the container, there being circumferentially spaced openings in thewalls of the cylinder intermediate its ends, a discharge pipe connectingthe cylinder with the spout, a piston having a valved opening throughwhich liquid in the container may flow by gravity to the interior of thecylinder as the piston is moved downwardly to a point between thecircumferentially spaced openings in the cylinder whereupon the liquidin the container may flow directly into the cylinder above the piston tobe forced out through the discharge pipe when the piston is movedupwardly, and means exteriorly of the base and in vertical alignmentwith the spout for operating the piston.
